If you’re considering…

If you’re considering installing an intruder alarm, one of the first decisions you’ll need to make is whether to choose a monitored alarm system or an unmonitored (bells only) alarm.

Both options provide protection and act as a deterrent to criminals, but they work in different ways and suit different types of properties and users. Understanding how each system works can help you decide which level of protection is right for your home or business.

In this article, we answer some of the most common questions CIA receives from customers about monitored and unmonitored alarms.

What Is An Unmonitored Alarm System?

An unmonitored alarm system (often called a bells only alarm) operates independently. When the system is triggered, it activates internal and external sirens to alert anyone nearby that an intrusion has occurred.

Most modern systems can also send alerts directly to your phone so you can check what’s happening remotely.

However, because the system is not connected to a monitoring centre, it relies on you, a neighbour, or a passer-by to respond to the activation.

Advantages of an unmonitored alarm:

• No monthly monitoring subscription
• Simple to operate and maintain
• Still provides a strong visible deterrent

For many homes and small business premises, a bells only alarm alone can be enough to deter intruders.

However, it’s worth considering what would happen if the alarm activates while you’re away or unable to respond.

What Is a Monitored Alarm System?

A monitored alarm system is connected to a professional Alarm Receiving Centre (ARC) that monitors your system 24 hours a day.

If your alarm is triggered, the monitoring centre receives an alert and can immediately investigate the activation. Depending on the setup, they may:

• Contact you or your nominated keyholders
• Dispatch an alarm response officer
• Notify the emergency services where appropriate

This means there is always someone available to respond to an alarm activation, even if you are asleep, unable to answer your phone, or on holiday.

What Happens If My Alarm Goes Off?

With a monitored system, trained operators at the Alarm Receiving Centre assess the alarm signal and follow a pre-agreed response procedure.

This may involve calling you, contacting a keyholder, or sending a security officer to investigate the activation. In some cases, they may also contact the police or other emergency services if a genuine incident is confirmed.

With an unmonitored system, the alarm will simply sound until someone attends the property and resets it.

What Is a Keyholder?

A keyholder is a trusted person nominated to respond if your alarm is activated.

This could be a friend, neighbour, or family member who has access to your property and understands how the alarm system works. Alternatively, many businesses and homeowners choose a professional keyholding service, where a security company holds keys and attends the property if an alarm is triggered.

Is There A Cost Difference?

Yes, the main difference between monitored and unmonitored systems is the ongoing monitoring cost.

Unmonitored systems generally involve a one-off purchase and installation cost, and then ongoing servicing costs. Monitored systems usually include an additional monthly or annual fee to cover the monitoring service.

While monitored alarms cost more, many customers feel the added security and faster response provide valuable peace of mind.

Some insurance providers may also offer reduced premiums for properties with professionally monitored alarm systems.

Which Type Of Alarm Is Best?

There isn’t a single answer that suits everyone. The right choice depends on your property, budget, and how much responsibility you want to take in responding to an alarm activation.

In general, an unmonitored alarm may suit you if:

• You want a lower-cost solution
• You’re usually nearby and able to respond quickly
• You have neighbours or staff who can assist

A monitored alarm may be better if:

• You want 24/7 professional oversight
• You travel frequently or leave the property unattended
• Your insurance policy requires monitored security
• You want the reassurance that someone will respond to every alarm activation

Monitored systems are particularly common for businesses, larger properties, or premises with higher security risks.
